Code-First Developers, Your Wait Is Over: Blackbird Now Generates OpenAPI Specs from Code

Remember when we launched our GitHub integration for API Discovery back in May? We promised something special was coming for all you code-first developers. Well, that day has arrived.

From Code to Spec in Seconds

Our second GitHub integration feature is now live: automatic OpenAPI spec generation from your existing code. Whether you're dealing with legacy services that never got properly documented or you're part of a fast-moving team that ships code first and documents later, Blackbird now meets you exactly where you are.

Perfect for Real-World Development

Let's be honest—not every team starts with a perfect OpenAPI spec. Sometimes you inherit a codebase with zero documentation. Sometimes you're moving so fast that the spec becomes an afterthought. Sometimes you're working with microservices that were built by developers who are no longer with the company (we've all been there).

With our new spec generation capability, you can:

  • Document legacy APIs instantly without starting from scratch
  • Surface undocumented internal services that have been hiding in your repos
  • Onboard existing codebases into Blackbird in minutes, not days
  • Bridge the gap between implementation and documentation

How It Works

Simply point Blackbird at your GitHub repository, and we'll scan your code to automatically generate OpenAPI specifications. The generated specs are immediately available in your Blackbird workspace where you can refine, validate, and collaborate on them—all while keeping Git as your source of truth.

The Complete GitHub Integration Story

Now that both features are live, Blackbird offers the complete GitHub integration experience:

  1. API Discovery: Automatically imports existing OpenAPI specs from your repos
  2. Spec Generation: Creates OpenAPI specs from your code when specs don't exist
  3. Bi-directional Sync: Keeps everything up-to-date as your code evolves

Whether you're design-first or code-first, Blackbird adapts to your workflow while helping you eliminate API sprawl and improve collaboration across your team.

Ready to Clean Up Your API Ecosystem?

Stop letting undocumented APIs hide in your repositories. With Blackbird's complete GitHub integration, you can finally have that centralized, collaborative, always-accurate home for all your APIs—regardless of how they started life.

Because sometimes the best API documentation is the one that writes itself.
